To observationally explore physical processes , we present a multi-wavelength study of a wide-scale environment toward l = 13 \arcdeg .7–14 \arcdeg .9 containing a mid-infrared bubble N14 .
The analysis of ^ { 12 } CO , ^ { 13 } CO , and C ^ { 18 } O gas at [ 31.6 , 46 ] km s ^ { -1 } reveals an extended physical system ( extension \sim 59 pc \times 29 pc ) , which hosts at least five groups of the ATLASGAL 870 \mu m dust clumps at d \sim 3.1 kpc .
These spatially-distinct groups/sub-regions contain unstable molecular clumps , and are associated with several Class I young stellar objects ( mean age \sim 0.44 Myr ) .
At least three groups of ATLASGAL clumps associated with the expanding H ii regions ( including the bubble N14 ) and embedded infrared dark clouds , devoid of the ionized gas , are found in the system .
The observed spectral indices derived using the GMRT and THOR radio continuum data suggest the presence of non-thermal emission with the H ii regions .
High resolution GMRT radio continuum map at 1280 MHz traces several ionized clumps powered by massive B-type stars toward N14 , which are considerably young ( age \sim 10 ^ { 3 } –10 ^ { 4 } years ) .
Locally , early stage of star formation is evident toward all the groups of clumps .
The position-velocity maps of ^ { 12 } CO , ^ { 13 } CO , and C ^ { 18 } O exhibit an oscillatory-like velocity pattern toward the selected longitude range .
Considering the presence of different groups/sub-regions in the system , the oscillatory pattern in velocity is indicative of the fragmentation process .
All these observed findings favour the applicability of the global collapse scenario in the extended physical system , which also seems to explain the observed hierarchy .
